An as of yet unknown Sony device bearing model number C6903 has made its way onto Indonesia’s POSTEL site. The model number, which starts with C6, suggests that this could be a high-end device.

Judging by the previous version numbers allocated to high-end devices, such as C660X which was given to the Xperia Z, and C650X, which was assigned to the Xperia ZL, it looks like this new device will similarly be a high-end device, possibly the 6.44-inch Sony Xperia ZU that has been seen in a set of leaked images lately. The Xperia ZU (Togari) allegedly features Qualcomm’s latest Snapdragon 800 SoC according to a benchmark. The other contender could be the Honami, which also is said to feature the Snapdragon 800 SoC.

However, the Xperia Tablet Z Wi-Fi was assigned a version number C6907, so we could just be looking at the LTE variant of the Xperia Tablet Z as the 3 at the end of the model number means that this device would support LTE networks.
